Abstract

The silica-silica interaction parameter (${\alpha}_F$) of the silane treated silica filled natural rubber (NR) compound was investigated. The measured ${\alpha}_F$ values using mass fraction method following Wolff's theory were compared with volume fraction method. As silica concentration increased, the ${\alpha}_F$ value increased for both methods. The value of ${\alpha}_F$ expressed as volume fraction was higher than that of mass fraction, which resulted in large gaps between ${\alpha}_F$ values. The effect of accelerator (MBT) concentration on ${\alpha}_F$ values was compared.

실란처리된 실리카가 천연고무 복합소재 내에서 실리카 간의 구조 발달 상수 ${\alpha}_F$에 미치는 영향을 비교하였다. 기존의 질량분율로 표시하던 Wolff의 방법을 본 실험에서는 부피분율을 사용하여 Wolff의 값과 비교하였다. 두 표현방식 모두 실리카의 함량이 증가할수록 ${\alpha}_F$값이 증가하는 경향을 보였다. 또한 부피분율로 표현하였을 시 ${\alpha}_F$값 간의 차이가 더욱 커지는 것을 관찰하였다. 따라서 부피분율로 표현하는 것이 ${\alpha}_F$값의 차이를 관찰하는데 있어서 기존에 질량분율을 사용하는 Wolff의 방법 보다는 차이를 뚜렷하게 나타낼 수 있다는 것을 관찰하였다. 또한 촉진제의 양을 변화시켜 관찰한 ${\alpha}_F$값의 변화와 비교하였다.
